ABSTRACT:
A piezoelectric on-off value for air conditioning comprises a bendable metal plate fixed at one end thereof; a valve member mounted on the other end of the metal plate along a ceiling plate, the value member having vent holes corresponding to vent holes in the ceiling plate, and the valve member changing the relative closure of the vent holes when the metal plate is deformed by application of voltage to the piezoelectric ceramic.
